Sorry for the delay... I have been troubleshooting the existing design before testing whether the ESP API functions will return when *full* rather than CS deasserting. FWIW, I asked Claude if that (Return when full) were true, and it pointedly disagreed (see below -- but it told me to burst in the ...

Hello there. We are using an STM32H7 as a SPI master connected to our ESP32-S3 as a slave. I've read over the documentation on how to code the ESP32 end, below:

Oh, great... no we are implementing a circular log over a span of blocks using the Partitions API, which will be sort of naturally wear-leveled. So I'm glad to hear that that eliminates the need for bad block management. I thought I remembered that the bad blocks could appear over time, and was a ...

We are using a ESP-32 dev kit (ESP32-C6-DevKitC-1), and using the partitions API to read and write to FLASH, and it works well.

It's been a while since I've written code for nonvolatile FLASH... I seem to recall the need for a mechanism called bad block management, in which you scan for blocks that ...

Thank you ok-home, you are right that was the problem. Not sure why the dev kit would come shipped with this problem...

UPDATE: this is happening on two different boards, and I don't seem to be able to find ANY example code that sets up UART0 for receiving. This is getting absurd, the most basic function on a controller and I can't get it to work. Does anyone have any theories, or a pointer to some code that should ...

Hello, I'm trying to write some UART code to talk to my ESP32c6-DEVKITC1. I am able to read and write through UART1 through pins 10 and 11, with the first code snippet below. But I am not able to talk through UART0 through pins U0TXD/GPIO16, U0RXD/GPIO17, using the second code snippet below.

Is ...

Thank you MicroController. I do get that, that FLASH memory generally requires erasing a page at a time, and we have some reusable roll-your-own code that manages that (copies page out, edits, erases original page, writes modified page). I will definitely look into the libraries you mention (SPIFFS ...

Hello, we are getting started using an ESP32c6, and we would like to implement some light custom database functionality, using nonvolatile storage.

I see that the NVS library is available, but that it's "designed to store key-value pairs in flash."

I think that's (key value pairs) not exactly the ...
